To all whom it may concern 4 Be it known that I, CHARLES J. REILLY,

a citizen of the United States, residing at Catskill, in the county ofGreene and State of New York, have. invented. a certain new and usefulImprovement in Furnaces for ;Water-Heaters, of which the following is aspecification.

This case is a divisional application of 1N0. 858,603, Charles J.Reilly, water heater,

filed Aug. 26, 1914.

My invention relates to furnaces for water heating, devices,particularly such as are adapted for the use of various kinds of oil,

such as kerosene, as fuel.

One form of my invention is illustrated in theaccompanying drawingswherein- Figure 1 15 a diagrammatic side elevation, with parts showingon dotted linesFig. 2

is a cross section of the heater,Fig. 3 is a plan section of the same,as indicated on line 3-3 of Fig. 2,Fig. 4 is a perspective ofthe airvalve ringFig. 5 is a vertical cross section of the generator.

Like parts are indicated by the same letter in all figures.

. For purposes of illustrationI have shown.

my invention in connection with an ordinary range or furnace hot waterb01161, which may be an ordinary receptacle for holding hot water underpressure. In view r of the necessity of such device for use in heatingwater in the household, "and for many commercial purposes in thermaldistricts, cities, towns and villages, where no M artificlal or naturalgas can be secured'for the purpose, and where gasolene if used for thepurpose is dangerous to life and property, I have invented anarrangement in which ordinary kerosene or crude oil can be used for thepurpose efficiently without fear of any danger, externalheat orobnoxious odors. The greatest benefit will be derived in many cases bythose who have a water heating apparatus connected'to a furnace or coalcook stoves, only used for a few monthsv in each year, thusnecessitating resorting to I laborious and troublesome means of secur=the furnace.

' ing hot water for the bath or other household or commercial purposes.My invention can be connected up with, and withoutdisturbing any otherarrangement for heating B is a cylindrical heater housing containing-theheating coil B whence leads the pipe 0 C respectively tothe top andbottom of the receptacle A. The heaterB is connected with the source offuel supply D, the fuel in this case being'kerosene, by means ofthe-pipe E, which leads downwardly from the reservoir and passes throughthe wall of F is a valve to regulate the quantityof oil passing throughthe pipe E. V

G is a generator, the essential part of which is the annular part G withscrew threaded hollow projections, Gr on its opposite sides and acentral'plate G Into one of these connections G leads thev pipe E J andfrom the other emerges the pipe G which is shaped as shown andterminates in the cap H, perforated to allow theliquid in the pipe-toescape andplaced beneath the plate G Thisplateacts as a baffle todistribute the upwardly flowing gas. a g The furnace consists of thecasing K, with the fire brick lining I. a

J J are perforationsthrough the casing and fire brick lining I. g

J J are perforations in the valve ring L, which is supported in theannular support M, and whose two ends are adapted to be drawn togetherby the thumb screw N to lock it in any desired position. The quan-.

tity of air is regulated by moving and setting this valve ring. V

In the heater housing B is the coil B connectedwith pipes .C at top' andbottom as indicated. I use a double conical coil as indicated with thebaffle plate P at the middle and narrowest portion to prevent the hotgases from passing up through the Gen ter of the coil. 7

loose bed of asbestos U to absorb the oil that is allowed to run out ofthe perforation in the cap H for use inheating up the generator instarting up the apparatus V is a tube leading from the water circulatingpipe C down to just above the baffle plate of the generator, and it iscontrolled by the valve V. Through it water may be discharged upon thebaflie plate.

X is an auxiliary reservoir and Y a valve connected with the pipe E,whereby the supply of kerosene may be cut off when the auxiliaryreservoir is full, the latter being a charge for a specific piece ofwork or time.

Z is the cold water inlet pipe which leads I to the bottom of thereceptacle A, and Z the hot water service pipe which leads from the topthereof.

Z is a stand or bracket on which the receptacle is supported, and Z is alike stand or bracket on which the furnace is supported.

X is a check valve or air release communicating with the reservoir X topermit air to enter at the top to displace the liquid which runs outwhen the valve Y is shut and the valve F is open. It, however, does notpermit the discharge of oil'when the system is full.

The use and operation of my invention is as follows: The cold water andthe hot water pipes are connected to the distributing system of thehouse in such manner that the receptacle stands full of water, and undernormal conditions this water will be cold. If now, the operator desiresto heat the water, he will turn the valve ring L so as to expose theinteriorof the furnace. He will then open the valves Y and Fsufliciently to allow oil to enter through the pipes E and G to theinterior of the furnace and into the bed of asbestos U in the bottom ofthe furnace. He now closes valves Y and F, and by match or taper lightsthe oil in the asbestos within the furnace, and this oil burning willbring the generator to such a temperature as will cause the formation ofgas. The operator now opens the valves Y and F, whereupon the oil whichpasses through the pipe E into the generator emerges from the cap H asgas, and as such it is immediately burned.

The products of combustion pass upwardly through the top of the furnace,through the heater, and 1f the damper S is open, out through the stackand chimney into the open air. Such products of combustion however, passlaterally upwardly through the coils B being deflected by the baflieplate P, so that at that point all of the products of combustion willhave passed through the lower set of coils and thereafter will passinwardly through the upper set of coils, thus heating the water whichpasses through these coils.

If the operator desires to heat a certain specified amount of water orto have the apparatus run for a predetermined period, he will open thevalve Y, or otherwise manipu late the valves so that the auxiliaryreservoir X fills with oil, and he may then close the valve Y andproceed as above, whereupon the tire will be maintained only so long asthe oil in the auxiliary reservoir lasts.

In apparatus of this kind trouble is frequently experienced with respectto the formation of soot and like deposits on the coils. For this reasonI provide the pipe V and controlling valve 7, so that when the valve WVis open a certain amount of water will pass through the heater and bedischarged upon the hot baflie plate G when it is im mediatcly convertedinto steam, and this steam serves to clear the exterior surfaces of thecoils of the deposits thereon due to the passage of the products ofcombustion.
